•
Set the IP Address Type to Dynamic on the IPv4 Interface page, as
described in the
Use the DHCP Auto Configuration page to perform the following actions when the
information is not provided in a DHCP message:
•
Enable the DHCP Auto Configuration feature.
•
Configure the switch to receive configuration information from a specific file
on a specific server.
Note the following regarding the DHCP Auto Configuration process:
•
A configuration file that is placed on the TFTP server must match the form
and format requirements of the supported configuration file. The form and
format of the file are checked, but the validity of the configuration
parameters is not checked prior to loading it to the Startup Configuration.
•
In IPv4, to ensure that the device configuration functions as intended, due to
allocation of different IP addresses with each DHCP renew cycle, we
recommend that IP addresses be bound to MAC addresses in the DHCP
server table. This ensures that each device has its own reserved IP address
and other relevant information.
DHCP Auto Configuration is applicable only when the IP address of the switch is set
to dynamic.
To configure DHCP Auto Configuration:
Click Administration > File Management > DHCP Auto Configuration.
Enter the following information:
•
Auto Configuration via DHCP—Check Enable to enable the DHCP Auto
Configuration feature on the switch, or uncheck to disable this feature.
•
Backup Server Definition—Select whether to specify the TFTP server by
IP address or domain name.
•
IP Version—Select either Version 4 or Version 6 if the TFTP server is
identified by IP address.
•
Backup TFTP Server IP Address/Name—Enter the IP address or domain
name of the backup TFTP server. If no configuration file name is specified in
the DHCP message, the switch will download the backup configuration file
from the backup TFTP server.
